I have an Eaton M62 supercharger and I cannot find a straight answer on if I should replace the oil in it. And, if so, when?
The GM manual says it is a closed system that never needs servicing. Yet they go on to explain how to change it, which isn't hard.
Eaton recommends 100,000 miles, while other people are saying 20k, 40k, etc.
Any thoughts on this? Should I just not worry about it or should it become something I do regularly?
